Tumor Types

The newly described adhesive tumor cell culture system (ATCCS) offers a distinct advantage over other assays in that it has a high plating efficiency requiring low cell inoculum, it affords workable assays in approximately 70% of specimens from the heterogenous tumor types, and it has the ability to assay up to nine drugs at four different concentrations. Clinical correlations based on the ATCCS were obtained in 65 patients undergoing 71 clinical trials. Patients with melanoma, lung cancer, and sarcoma dominated the group. The most active in vitro drug was correlated per clinical trial. Thirteen of 17 (76%) sensitive in vitro predictions and 51 of 54 (94%) resistant in vitro predictions were accurate. The assay in this study had a sensitivity of 81% and specificity of 93%. These preliminary results are encouraging and warrant prospective trials to establish the true value of this assay to patients.

A Cell

A cell culture microfluidic device has been developed to test the cytotoxicity of anticancer drugs while reproducing multi-organ interactions in vitro. Cells were cultured in separate chambers representing the liver and tumor. The two chambers were connected through a channel to mimick the blood flow. Glioblastoma (GBM) cancer cells (M059K) and hepatoma cells (HepG2) were cultured in the tumor and the liver chambers, respectively. The cytotoxic effect of cancer treatment drug Temolozomide (TMZ) was tested using this two chamber system. The experimental results showed that with the liver cells, the cancer cells showed much higher viability than those without the liver cells. This indicates that the liver metabolism has strong effect on the toxicity of the anticancer drug. The results demonstrated that the perfused two chamber cell culture system has the potential to be used as a platform for drug screening in a more physiologically realistic environment.

AbstractBackgroundFunctional foods can help prevent metabolic diseases, and it is essential to evaluate functional characteristics of foods through in vitro and in vivo experimental approaches.ObjectiveWe aimed to use the bicameral cell culture system combined with the in vitro digestion to evaluate glucose bioavailability.Materials and methodsCake, almond paste, and pudding were modified by adding fiber and replacing sugar with sweeteners and polyols. Digestion process was modeled in test tubes. Rat enterocyte cells (IEC-6) were grown in a bicameral cell culture system to mimic the physiological characteristics of the human intestine. The glucose bioaccessibility and cellular glucose efflux were measured by glucose oxidase assay.Results and discussionThe glucose bioaccessibilities of modified foods were significantly lower (cake: 2.6 fold, almond paste: 9.2 fold, pudding 2.8 fold) than the controls. Cellular glucose effluxes also decreased in the modified cake, almond paste, and pudding by 2.2, 4, and 2 fold respectively compared to their controls.ConclusionOur results suggest that combining in vitro enzymatic digestion with cell culture studies can be a practical way to test in vitro glucose bioaccessibility and bioavailability in functional food development.
